The document discusses IBM's Capacity on Demand (CoD) program which allows customers to temporarily activate additional computing resources on an as-needed basis and pay only for what they use. It describes the different types of CoD options available for Power5 and Power6 systems including permanent activations, on/off CoD for temporary usage billed by the day, and trial CoD. It provides details on the implementation process, including registration, contracts, ordering enablement codes, activating and reporting usage, and billing. Customers can gain flexibility to respond quickly to changing needs while avoiding costs for unused capacity.
